No. 24
D/A Output Voltage at 100% Torque Limit Setting Range Setting Unit Default Value
1 to 10000 0.001 V 3000
Description
Set the D/A output voltage at 100% torque limit reference (and torque limit at speed reference).
Common for the positive and negative sides. Set the current limit value when using a SERVOPACK.
D/A output value =
Positive Side Limiting Torque/Thrust Setting at the Speed Reference (OL††14)
× D/A Output Voltage at 100% Torque
Limit (fixed parameter no. 24)/10000
Where D/A Output Voltage at 100% Torque Limit = 3 V, and Positive Side Limiting Torque/Thrust Setting at the Speed
Reference = 200%,
(20000
× 3 V)/10000 = 6 V. Therefore, 6 V is output.
No. 26
A/D Input Voltage at 100% Torque Monitor Setting Range Setting Unit Default Value
1 to 10000 0.001 V 3000
Description
Set the scaling value in units of 1 mV to convert the voltage input through the A/D converter to the torque monitor
value (%).
The torque monitor value is calculated as follows and stored in the monitoring parameter Feedback Torque/Thrust
(IL††42).
Torque monitor value = (A/D input voltage
× 10000)/A/D input voltage at 100% torque monitor (fixed parameter No. 26)
Where A/D input voltage at 100% torque monitor = 3 V, and the actual A/D input voltage = 1.5 V,
(1.5 V
× 10000)/3V = 5000. Therefore, 5000 is stored in IL††42.
No. 28
Servo Driver Type Selection Setting Range Setting Unit Default Value
0 to 2 − 1
Description
Set the series of servo drive that is being used.
0: Σ-I seires
1: Σ-II/Σ-III/Σ-V series (default)
2: Reserved for system use
No. 30
Encoder Selection Setting Range Setting Unit Default Value
0 to 3 − 0
Description
Set the type of encoder that is being used.
0: Incremental encoder
1: Absolute encoder (default)
2: Absolute encoder (Incremental encoder is used.)
3: Reserved for system use
ΠFor linear motors, set the encoder type that matches the settings of the linear scale and SERVOPACK
being used.
No. 31
Rotation Direction Selection with an Absolute Encoder Setting Range Setting Unit Default Value
0 or 1 − 0
Description
Set the rotation direction of absolute encoder.
0: Forward (default)
1: Reverse
Œ Set to 1 when “Reverse Rotation Mode” is set in the SERVOPACK parameter * when using an absolute
encoder applicable SERVOPACK.
* For SGDA and SGDB SERVOPACKs, Cn02, bit 0 = 1 (Reverse rotation mode)
For SGDM, SGDH, SGDS, or SGDV SERVOPACKs, Pn-000.0 = 1 (Reverse rotation mode)
ΠRefer to 11.2.3 Rotation Direction Selection on page 11-12 for details of reverse rotation setting of SERVO-
PACK parameter.
